Worries about Europe — particularly regarding a Spanish corruption scandal and Italy’s election — and a sliding euro left stocks in the red for the day, sending them down from previous five-year highs and sinking the Dow Jones Industrial Average back below 14,000.

The Dow was the day’s “best” performer — little consolation for its triple-digit drop to 13,880.08, or -0.93% lower. The S&P 500 fell 1.15% — its biggest decline of the year — to 1,495.71, and the Nasdaq lost 1.51% to end at 3,131.17.

The Commerce Department did report a rebound in U.S. factory orders for December, but the 1.8% increase was still smaller than expected. News also broke that Standard & Poor’s will face a lawsuit from the U.S. Justice Department over mortgage bond ratings before the financial crisis.

Oracle (NASDAQ:ORCL) slipped nearly 3% on the news that it will pay around $2 billion for network gear maker Acme Packet (NASDAQ:APKT). Shares of Acme, on the other hand, jumped 24% overall — more than the 22% premium paid by Oracle.

Blackberry (NASDAQ:BBRY) — which just switched from its previous name of Research In Motion — was another big gainer on the day. Investors sent BBRY up to the tune of 15% after Bernstein Research upgraded it to “outperform.” The company debuted its new BB10 smartphone last week.

On the earnings front, media conglomerate Gannett (NYSE:GCI) shed nearly 7% after the company reported a drop in net income for the fourth quarter despite a bump in broadcasting and digital ad sales. Royal Caribbean Cruises (NYSE:RCL) also found itself in the red today, losing more than 3%. The company lost nearly $400 million during Q4 thanks to weak European demand.

Bucking the trend was healthcare company Humana (NYSE:HUM), which gained around 5% despite a nearly 4% dip in profits. Its earnings of $1.19 per share on revenue of $9.6 billion handily beat analyst expectations of $1.06 per share on revenue of $9.73 billion.

Notable earnings on Tuesday include Zynga (NASDAQ:ZNGA) and Disney (NYSE:DIS).
